Could life exist on Venus?

Most astronomers feel that it would be impossible for life to exist on Venus. Today, Venus is a very hostile place. It is a very dry planet with no evidence of water, its surface temperature is hot enough to melt lead, and its atmosphere is so thick that the air pressure on its surface is over 90 times that on Earth. Even the spacecraft which have landed on Venus only survived for about an hour before being crushed and melted. There are however, a few scientists who think that it is possible for life to exist in the clouds of Venus. - caltech
